Then there are those who have a strong eco-conscience, don’t eat meat, ride bikes, and shop second hand. And finally, there are folks who live entirely without money. But everyone could use a gentle reminder once in a while. Hu2 Design’s stickers show everybody the hidden costs behind household choices.

The sticker on the left represents three windmills, and on the right, a graphic depiction of water power.

What’s a hamster got to do with it? A house powered by hamster’s kinetic energy, perhaps? Who knows, but it’s still cute.

These stickers are a bit easier to identify. There’s the oil spill on the left, that brings up BP Gulf nightmares, and the CO2 spewing from fossil-fueled factories.

There goes the hamster again, scurrying like mad to light up the room!

It’s a silly thing really, but HU2’s designs demonstrate a kind of lighthearted approach to what is clearly a very serious issue. That takes the edge off things, and perhaps makes it a little easier for people to make the right choice.
